Well, if they are into it, it's definitely a one on one thing, because she didn't seem to be enjoying it with both Sebastian and Sheridan. Come to think of it, maybe that's proof they aren't since 3 is such a "Holy" number with the Minbari

I also suspect that Delenn and Sheridan viewed Sebastian as "the most extreme," i.e. the worst the Vorlons were willing to do. It was a test, they knew it was a test -- and I really doubt they felt Sebastian was spouting the Vorlon party line. In fact I'm not sure they believed anything he said or argued for until the very end when he told them they had passed. It took the form of very, very extreme Socratic questioning. Such a questioner/inquistor does not necessarily believe what he is saying at any point: he's making sure that the person under examination is doing "the right thing."

As for cruelty -- well, the Minbari and Delenn in particular had some experience with "being cruel to be kind." Witness their terrible choice about heeding G'Kar's warnings or not.

Sebastian was probably, to their minds, either a sadistic Socrates or practicing a sort of necessary brutality. As they did not know the true Vorlon agenda, any excesses Sebastian carried out could have easily been explained away. And considering how desperate the Conspiracy of Light was for backup, the excesses would have been glossed over in any way possible.

I really like this episode, Wayne was great.
About Delenn and Sheridan being so fools, I think the problem was that everyone was blinded by Vorlons. Dukhat said to Delenn: (ItB) (more or less) "when you have a doubt, look at the face of a vorlon".
They all were deceived. They were used by the Vorlon and they realized it 2 years later.
So, how Delenn was gonna deny to be questioned if a Vorlon asked for it ?
Sometimes it seems as if she was ready to die for Kosh.

Hello there, Acheron. Now that is an excellent point. Millenia of mental and genetic conditioning had made the Vorlons instinctively trusted beyond all logic or reason. Look what Lyta put herself through just to have a slight chance of contacting them.

IIRC, he was Jack, Lorien, the Drakh in s5 (Shiv'k'la or something), the Drazi in Intersections in real time, and various other bits requiring a decent actor behind an alien mask.

Ah, thanks Penny.

I knew he played a few parts, and I forgot what the others were. Rewatching the old Star Trek episodes (Next Generation and Deep Space Nine) I see how many actors returned in different roles in the Star Trek universe.

What's interesting about "Sebastian" is that I never recognize his voice. That's usually how I spot the repeat players in Star Trek.
